Space Channel 5: Part 2 (スペースチャンネル5 パート2) is the sequel to the rhythm action game Space Channel 5, developed by United Game Artists and published by Sega. It was simultaneously released in Japan for the Sega Dreamcast and PlayStation 2 on February 14, 2002, the PlayStation 2 version later being released in Europe later in the year.

With its improved graphics, greater variety, and longer campaign, Part 2 is generally regarded as superior to its predecessor. Like its predecessor, it stars Ulala and has a cameo by Michael Jackson, known in this game as "Space Michael".

Gameplay

Whilst the scoring system is much different from the first game, the core gameplay in Space Channel 5: Part 2 remains mostly unchanged from its predecessor. Ulala, the star of the game, must copy moves acted out by the opponent in time to the music by pressing the directional buttons and two "firing" buttons, / ("Chu!", known as "Shoot" in the first game), and / ("Hey!", also known as "Shoot" in the first game, despite having a different effect on play). "Chu! is used to shoot enemies and objects, while hostages can be rescued with "Hey!".

New to Part 2 is the ability to hold buttons down as a "charged move" (for example when someone says "Chuuuuu---", the player holds the / button). Also new to the game is some segments that involve instrument battles, which are played using any directional button, as well as Chu! and Hey!.

Usually in the game, players have a set number of hearts, which varies depending on the situation. If they mess up a section, they lose a heart, and if all hearts are lost, the game is over. In some sections, such as boss battles, stars replace hearts, the number of which is determined by the current rating (the higher the rating, the more stars will be available). If all stars are lost, the game is over.

The viewer rating percentage in the corner works as the score, which changes depending on how well the game is played and the number of hearts or stars at the end of a scenario. There are also secrets at certain points in between gameplay where players press buttons to make Morolians (the enemies from the last game, now allies), spring up from the corner. Players need to find all these secrets in a level in order to get a full 100% rating at the end (the last level has a possible 200% rating).

Elsewhere, there is a 100 stage battle mode, in which players have to play 100 consecutive lines, with only one heart. Some of the lines seem to resemble those found in the first game. There is also a 2 player mode, where one player controls directions and the other controls actions, and an alternate story mode where characters, costumes and dance moves are different.

Other improvements include replacing the pre-rendered backgrounds of the first game with real time environments.
